 If you just want to use kernel-doc to generate man pages you can do this
 from the kernel git tree::
 
-  $ scripts/kernel-doc -man $(git grep -l '/\*\*' -- :^Documentation :^tools) | scripts/split-man.pl /tmp/man
+  $ scripts/kernel-doc -man \
+    $(git grep -l '/\*\*' -- :^Documentation :^tools) \
+    | scripts/split-man.pl /tmp/man

+    | scripts/split-man.pl /tmp/man
+
+  $ scripts/kernel-doc -man \
+    $(git grep -l '/\*\*' -- . ":(exclude)Documentation" ":(exclude)tools") \
